The main objective of this study is to evaluate the long-term safety of CP-690,550 in patients being treated for moderate to severe chronic plaque psoriasis. This is an open label extension study available to patients who participated in one of the qualifying studies with CP-690,550 providing entry criteria is met.

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline up to 4 weeks after last dose of study drug (up to a maximum of 67 months) ]

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to 4 weeks after last dose (up to 67 months) that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious adverse events.

Number of Adverse Events (AEs) by Severity [ Time Frame: Baseline up to 4 weeks after last dose of study drug (up to a maximum of 67 months) ]

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. AEs were classified according to the severity in 3 categories: a) mild: AEs did not interfere with participant's usual function; b) moderate: AEs interfered to some extent with participant's usual function; c) severe: AEs interfered significantly with participant's usual function.

Number of Participants With Laboratory Abnormalities [ Time Frame: Baseline up to 4 weeks after last dose of study drug (up to a maximum of 67 months) ]

The PGA of psoriasis was scored on a 5-point scale, reflecting a global consideration of the erythema (E), induration (I), and scaling (S) across all psoriatic lesions in participants. The severity rating scores (Erythema: 0= no evidence of erythema to 4= dark, deep red; Induration: 0= no evidence of plaque elevation to 4= marked plaque elevation, hard/sharp borders; Scaling: 0= no evidence of scaling to 4= thick, coarse scale predominates) were summed (E + I + S = total) and the average (total/3) was taken. The total average was rounded to the nearest whole number score to determine the PGA. The 5-point scale for PGA was: 0= clear; 1= almost clear; 2= mild; 3= moderate; 4= severe, where higher score indicated more severity of psoriasis. Percentage of participants with response of 'clear' (score of '0') and 'almost clear' (score of '1') were reported.

ISI assessed severity of itching due to psoriasis. ISI was a single item, horizontal numeric rating scale. Participants were asked to rate their 'severity of itching' due to psoriasis over the past 24 hours on a numeric rating scale anchored by the terms '0=no itching' and '10=worst possible itching' at the ends. Higher scores indicated greater severity of itching.

The DLQI was a validated, self-administered, 10-item quality-of-life questionnaire that consisted of 10 items that assessed the impact of skin disease on quality of life (daily activities, personal relationships, symptoms and feelings, leisure, work and school, and treatment). Each question was scored on a scale of 0=not at all/not relevant to 3=very much. Response from all of the 10 questions were added to derive the DLQI total scores. Total DLQI scores ranges from 0=not at all to 30=very much, with higher scores indicating greater impairment in quality of life.

The SF-36 questionnaire, version 2 was a 36-item generic health status measure. SF-36 evaluated 8 health-related aspects of an individual: physical functioning, role-physical, bodily pain, social functioning, mental health, role emotional, vitality, and general health. The score range for each of the 8 health aspects ranged from 0 (worst) to 100 (best), with higher scores indicating good health condition. Two summary scale scores were computed from the 8 health aspect scores: the Physical Component Summary and the Mental Component Summary. Score range for both summary scale ranged from 0 (worst) to 100 (best), with higher scores indicating good health condition.

The PtGA evaluated the overall skin disease of participants at that point in time on a single-item. Participants provided their response on a 5-point scale ranges from: 0=clear, 1=almost clear, 2=mild, 3=moderate, 4=severe. Higher score indicated greater severity of disease. Participants who provided their response as "clear (score of 0)" or "almost clear (score of 1)" in PtGA at each specified visit were reported in this outcome measure.

EQ-5D: participant rated 5-dimension (mobility, self-care, usual activities, pain and discomfort, and anxiety and depression) questionnaire to assess health-related quality of life in terms of a single utility score. Each dimension was assessed on a 3-point scale (1=no problems, 2=some problems, 3=extreme problems, where higher scores=worse health condition). The responses from the 5 dimensions were used to calculate a single utility index value. Scoring formula developed by EuroQol Group assigned a utility value for each dimension in the profile. Score was transformed and results in a total score range -0.594 to 1.000; higher score indicated a better health state.

EQ-5D VAS was a participant rated questionnaire to assess health-related quality of life in terms of a single index value. It was a visual analogue scale that ranged from 0 (minimum) to 100 (maximum), with higher scores indicating a better health condition.

Ps-HCRU was a short questionnaire designed to assess healthcare resource use and the impact of psoriasis on work. In the first section, it assessed direct costs associated with healthcare resource use which included participant's interactions with healthcare providers such as general practitioners, dermatologists, cardiologists, gastroenterologists, psychiatrists, surgeons and nurses. When taking the evening dose of tofacitinib, participants were asked to answer the Ps-HCRU questionnaire only if they had an interaction with a healthcare provider or their work was impacted by psoriasis on that specified day. In this outcome measure, number of participants who answered Ps-HCRU at any specified visits were reported.
